Ratings and reviews

Of all the software calculators I have used over the past 22 years, RealCalc is the best by a wide margin. Transitions between number bases is easy; important to me because I work in hexadecimal all day. Yet it's a strong accounting calculator when I need that; not to mention fraction calculations when I'm in the shop. Settings give it flexibility beyond my usage needs. I bought the Plus version when I saw how much I was using it and have been completely satisfied.

I just now purchased the upgrade after using the free version for close to a decade -- and I use it every day. I didn't even care about or pay $3.49 for what the upgrade offers, but rather felt the usefulness I've received from the free version all these years finally deserved some remuneration. My experience (or, at least with the free version) is that it's a simple, standard calculator, but it works *really well*. Brava Quartic. Looking forward to seeing what the upgrade can do.

Excellent calculator! I'm a computer engineer and love the conversion to different number formats, hex, dec, bin. The haptic feedback is also a nice touch. Feels like I'm using a real calculator! The author did an excellent job with this nice piece of software. Very impressed with all the conversions as well. The free version is good but purchase the paid for version for the extra set of features and to just give some money back to the author for the hard work and constant updates.
